Can i put potting mix or dirt of soil in water forming a slurry and use it as hydroponics nutrient solution?
I recently saw videos on hydroponics and wanted to set it up my self on a budget, 0$, just as an experiment i cut the cone top of a small mineral water bottle put it upside down like a diy minnow trap and used tissue as substitute for rock wool, filled bottom with water till it just touched the tissue, then plopped a bean in it. I then forgot after putting it behind a fish tank. After 3 days it looks like this. I need nutrient in water so i was thinking about just dumping a palm full of soil, would it work?
